Went into it determined to get 5 circuits, which was unrealistic. At the end of the third I thought it was possible because everything had been done in one go til that point. Break for breath and water between circuits nothing else.
Squats in circuit 4 were my first introduction to the fact 5 might not be possible, set of 10 became 3, 5, 8, 10 due to having to rerack 3 times in the set. By the time I got to the end I mustered a last bit of adrenalin to get the jumps done then had to concede defeat and stop.
I am happy to have done the whole thing without having to drop weight etc. and feel confident I will get 5 in the next week or 2, maybe six by the end of block. That is not likely to get me to 20 minutes, but I think aiming for that with those weights was too much anyway.
I guess intervals during lunch won't have helped though.
